2024 ICD-10-CM Diagnosis Code E00.1

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Congenital iodine deficiency syndrome
• Congenital iodine deficiency syndrome
• Endemic congenital iodine deficiency syndrome of myxedematous type
• Endemic cretinism
• Myxedema
• Myxedema
• Myxedematous form of cretinism

Clinical Information

• Congenital Hypothyroidism

  a condition in infancy or early childhood due to an in-utero deficiency of thyroid hormones that can be caused by genetic or environmental factors, such as thyroid dysgenesis or hypothyroidism in infants of mothers treated with thiouracil during pregnancy. endemic cretinism is the result of iodine deficiency. clinical symptoms include severe mental retardation, impaired skeletal development, short stature, and myxedema.

• Myxedema

  a condition characterized by a dry, waxy type of swelling (edema) with abnormal deposits of mucopolysaccharides in the skin and other tissues. it is caused by a deficiency of thyroid hormones. the skin becomes puffy around the eyes and on the cheeks. the face is dull and expressionless with thickened nose and lips.

• Scleromyxedema

  a connective tissue disorder characterized by widespread thickening of skin with a cobblestone-like appearance. it is caused by proliferation of fibroblasts and deposition of mucin in the dermis in the absence of thyroid disease. most scleromyxedema cases are associated with a monoclonal gammopathy, immunoglobulin igg-lambda.

• Congenital Iodine Deficiency Syndrome, Myxedematous Type|Congenital iodine-deficiency syndrome, myxedematous type

  congenital iodine deficiency syndrome associated with milder mental retardation, short stature, goiter, and hypothyroidism. it results from iodine deficiency and hypothyroidism in the fetus during late pregnancy or in the neonatal period.

• Myxedema

  a condition characterized by severe hypothyroidism that is caused by autoimmune thyroid gland disorders, surgical reduction of thyroid tissue, radiation exposure, and viral infections. signs and symptoms include generalized fatigue, lethargy, increased body weight, pale, edematous and thickened skin, low blood pressure, constipation and cold intolerance.

• Myxedema Coma|Myxedema coma

  a life-threatening condition characterized by altered mental status and defective thermoregulation. it is seen in individuals with severe, decompensated hypothyroidism.

• Scleromyxedema

  a rare chronic and progressive skin disorder characterized by mucin deposition in the skin, resulting in the thickening and hardening of the skin, predominantly in the face, fingers, and extremities.

• Systemic Atrophy Primarily Affecting the Central Nervous System in Myxedema|Systemic atrophy primarily affecting the central nervous system in myxedema

  evidence of systemic atrophy primarily affecting the central nervous system in myxedema.

• Endemic Cretinism

  severely reduced physical and mental growth associated with pyramidal and extrapyramidal signs and symptoms, due to dietary iodine deficiency.

E00.1 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
643	ENDOCRINE DISORDERS WITH MCC	10	1.6451
644	ENDOCRINE DISORDERS WITH CC	10	1.0617
645	ENDOCRINE DISORDERS WITHOUT CC/MCC	10	0.7609

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert E00.1 to ICD-9-CM

• ICD-9-CM Code: 243 - Congenital hypothyroidsm
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Thyroid Diseases

Your thyroid is a small, butterfly-shaped gland in the front of your neck. It makes hormones that control the way the body uses energy. These hormones affect nearly every organ in your body and control many of your body's most important functions. For example, they affect your breathing, heart rate, weight, digestion, and moods.

Thyroid diseases cause your thyroid to make either too much or too little of the hormones. Some of the different thyroid diseases include:

• Goiter, an enlargement of the thyroid gland
• Hyperthyroidism, which happens when your thyroid gland makes more thyroid hormones than your body needs
• Hypothyroidism, which happens when your thyroid gland does not make enough thyroid hormones
• Thyroid cancer
• Thyroid nodules, lumps in the thyroid gland
• Thyroiditis, swelling of the thyroid

To diagnose thyroid diseases, your health care provider may use a medical history, physical exam, and thyroid tests. In some cases, your provider may also do a biopsy.

Treatment depends on the problem, how severe it is, and what your symptoms are. Possible treatments may include medicines, radioiodine therapy, or thyroid surgery.
